I am trying to set up Internet Sharing so that I can connect my old MacBook Pro running 10.6.8 via ethernet to another device - I'm trying with xbox360 and Sony Blu Ray (BPD-S185) (for diversity of devices - I used to have it working on my xbox, but really want it working with the blu ray player but the network status feedback is better for problem solving on the xbox!). I have my MBP connected to my home network over Airport which has the following details: - IP: 192.168.1.5 - Router IP: 192.168.1.1 I have then enabled Internet Sharing through System Preferences to share my Airport connection to my Ethernet connection. I have the following Ethernet settings: - Configure IPv4: Using DHCP with manual address - (Ethernet) IP address: 192.168.2.1 - Subnet Mask: (blank - not user accessable, changes to 255.255.255.0 when xbox turned on) - Router: (blank - not user accessable) - DNS Server: 192.168.1.1 - Search Domains: (left blank) On the xbox I've set the network settings to: - IP: 192.168.2.2 - Subnet: 255.255.255.0 - Gateway: 192.168.2.1 - Primary DNS: 192.168.1.1 - Secondary DNS: 192.168.2.1 When I then select 'Test my Xbox Live Connection' it takes a while, the Network status shows 'Connected', however The Internet Failed. I am informed that the 'Test Failed' and 'more information' tells me I have an 'Internet Error' with the following Status codes: W: 0000-000B X: 0000-000D Y: 0000-0000 Z: 0000-0000 ID0004-000 L: 0015-10F1 Q: 8007-0435 T: Wired A: 192.168.2.2/255.255.255.0 G: 192.168.2.1 D: 192.168.1.1/192.168.2.1 So, it looks as though the problem lies with the MBP and internet sharing on OSX. I have extra suspicions that this is the problem, as connecting my Blu Ray player to my MBP via ethernet I also get a successful connection to the network, but no internet access. Pleeeeease can someone help?!?! This is driving me nuts - a couple of years ago I had internet sharing working to let my xbox connect to the internet, so what's happened in the last few years to mean this won't work?
